Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656020, here are decompositions:

29 + 8655991 = 8656020
53 + 8655967 = 8656020
67 + 8655953 = 8656020
83 + 8655937 = 8656020
97 + 8655923 = 8656020
101 + 8655919 = 8656020
103 + 8655917 = 8656020
137 + 8655883 = 8656020

Showing the first eight; more decompositions exist.
